btrfs_delalloc_release_extents - release our outstanding_extents : the inode to balance the reservation for. : the number of bytes we originally reserved with : do we need to free qgroup meta reservation or convert them.

When we reserve space we increase outstanding_extents for the extents we may add. Once we've set the range as delalloc or created our ordered extents we have outstanding_extents to track the real usage, so we use this to free our temporarily tracked outstanding_extents. This must be used in conjunction with btrfs_delalloc_reserve_metadata.

This will release the metadata reservation for an inode. This can be called once we complete IO for a given set of bytes to release their metadata reservations, or on error for the same reason.

btrfs_delalloc_release_space - release data and metadata space for delalloc : inode we're releasing space for : start position of the space already reserved : the len of the space already reserved : the len of the space we consumed or didn't use

This function will release the metadata space that was not used and will decrement ->delalloc_bytes and remove it from the fs_info delalloc_inodes list if there are no delalloc bytes left. Also it will handle the qgroup reserved space.

)

btrfs_delalloc_reserve_space - reserve data and metadata space for delalloc : inode we're writing to : start range we are writing to : how long the range we are writing to : mandatory parameter, record actually reserved qgroup ranges of current reservation.

This will do the following things

o reserve space in data space info for num bytes and reserve precious corresponding qgroup space (Done in check_data_free_space)

o reserve space for metadata space, based on the number of outstanding extents and how much csums will be needed also reserve metadata space in a per root over-reserve method. o add to the inodes->delalloc_bytes o add it to the fs_info's delalloc inodes list. (Above 3 all done in delalloc_reserve_metadata)
